Lovely and promising is a way of describing Minimus, which was in development back in 2012.
The preview that has managed to sneak out shows a decent animated main character who can jump around a sideways scrolling platform world, and moves very well in a fluid way. Although it is nothing more than a character test, with no enemies or other interactions – it is a good solid demo that indicates that this had a lot of promise.
It is possible that the title did get a bit further than this, but nothing has been forthcoming since the original preview release.
Why was it abandoned? We don’t know just yet. Maybe you can help us shed some light on it and what the plans were?
